If a tuning fork were applied to a person's forearm, they would perceive the vibration. Describe the response to the tuning fork by a "rapidly adapting" mechanoreceptor located in the forearm.

Expert Solution

Response to tuning fork by rapidly adapting mechanoreceptor :

Rapidly adapting mechanoreceptor is the most sensitive mechanoreceptor and responds to high frequency vibratiory stimuli.

Among the rapidly adapting mechanoreceptor panician corpuscle is the one that responds to vibrations and changes in pressure.

Panician corpuscle is the vibration sensitive receptor and each corpuscle innervates only one axon. They detect changes in pressure on yhe skin and transduce it to electrical energy.

When stimulus is applied to the skin (vibration by turning fork) a slight deformitation of any mechanoreceptor nerve cell ending results in electrical changes called receptor potential ,on the outer surface this in turn induces impulses in the nerve fibre.

MECHANISM OF ACTION :

The neuron at the center of panician corpuscle has special sodium ion channel to allow the sodium ions into neuron.

When pressure is applied the panician corpuscle changes its shape and there is inflow of sodium ions into neuron resulting in depolarization and generator potential.

This in turn induces action potential which reaches CNS by passing through neurons and appropriate response is coordinated from there.

Vibration from a 620 Hz tuning fork sets up standing waves on a string clamped at both ends (one of which you may take as x=0). The travelling wave speed on this string is 440 m/s. The standing wave has four anti-nodes and an amplitude of 2.0 mm. (a) What is the length of the string? ___ m (b) Write an equation for the transverse displacement of the string as a function of position and time: y(x,t) = ( ___...

Researchers (Hebl et al.,2009) were interested in whether European American (EA) individuals would perceive overweight EAs the same way that African American (AA) individuals would perceive overweight AAs. They asked a group of 45 EA female college students and a group of 21 AA female college students to rate photographs of overweight women of their own race; ratings indicated how positively they felt about the person (e.g., attractive, intelligent, successful, happy, etc.). EA group (n = 45): mean rating =...

Question 18: a. Describe what would happen to 100 g of wood chips that were spread on the ground in an area of temperate forest. Compare this outcome to the outcome you'd expect for 100 g of wood chips left in an arctic tundra ecosystem. What's different about the two ecosystems and how will it influence the outcome for the wood chips? b. Which of the following lakes would be most likely to develop an anoxic dead zone? Lake 1...
